Title: METHOD AND DEVICE FOR WIRELESS CHARGING
Abstract:
Embodiments of the present invention disclose a method and a device for wireless charging. The method comprises: a first terminal obtaining position information of a center of a second electromagnetic coil of a second terminal and angle information of the second electromagnetic coil with respect to a horizontal plane; determining, based on position information of a center of a first electromagnetic coil and the position information of the center of the second electromagnetic coil, position information of a wireless charging transmission path, and transmitting the same to the second terminal; the first terminal determining, based on the position information of the wireless charging transmission path and the position information of the center of the first electromagnetic coil, target angle information; if it is detected that current angle information of the first electromagnetic coil with respect to the horizontal plane does not match the target angle information, adjusting the current angle information of the first electromagnetic coil with respect to the horizontal plane; and charging, based on the adjusted first electromagnetic coil, the second electromagnetic coil. The embodiments of the present invention further disclose a corresponding device. The embodiments of the present invention facilitate improving wireless charging efficiency and reducing charging time.
